Understanding Reverse Osmosis And Its Effectiveness


Today, reverse osmosis (RO), is a term that is often used. It is frequently used in advertising for water purifiers. It was not used in a physics lecture ten years ago or by water purifier industry specialists. It is still important to be familiar with reverse osmosis as you will likely come across it. Let’s first look at what reverse osmosis is.

What Is Reverse Osmosis?

Reverse Osmosis allows contaminated water to pass through a semipermeable membrane. The membrane is only able to pass water molecules through it, while contaminants are left behind. You may be wondering why reverse osmosis is called that if it does not contain any trace of osmosis. The thing is, RO is a process that is critical to the operation of an It’s quite an efficient system, isn’t it? It may seem like the water has passed through many filters to be safe for drinking. Not quite, not yet. It is true that purification using a reverse-osmosis system works satisfactorily. Purified water can bring many benefits to your body. To achieve the best quality and benefits, water must be filtered through more than just RO.

A standard water purifier typically has two filters, apart from the RO membrane, prefilter, and postfilter. They can be placed either before or after the membrane. The sediment prefilter is usually coupled with a carbon filter, which removes volatile organic compounds (VOCs). After passing through the carbon filter, the water will remain completely colorless and odorless.

RO Filtration Steps

Let’s now look at how to purify contaminated tap water.

  • Prefiltration

The tap water flows through a pipe to the water purifier. It flows through to get rid of visible sediments, VOCs and goes through two prefilters.

  • RO Purification

The RO system filters the water moderately and then it flows through the membrane to the other side as pure water.

  • Storage Tank

The pure water is not directly transferred to the tap. It is stored in a tank until it fills up.

  • After Filtration

The purifier turns on immediately, and the water from the storage tank is filtered through one to two post-filters. It then flows out of the faucet, clear and ready to drink.

Efficacy Of An RO Water System

RO, as mentioned in the article, removes sediments, chlorine, and other visible and dissolved impurities. An RO system makes water taste good and doesn’t leave a bad odor. Filters also remove odor-inducing bacteria. The filters remove all impurities from tap water. Since most of it is collected behind the core membrane as waste or brine, there are increasing concerns about excessive water wastage. Ask yourself: Would you prefer to preserve water or risk causing harm to your body?

This is how reverse osmosis works on water. It doesn’t matter how polluted the water is. The majority of RO systems can filter even puddle water unless the main membrane or filters have been damaged. To ensure the best water quality, it is important to regularly clean the membrane and filters. Experts have confirmed that reverse osmosis systems can be used to effectively remove most viruses from water during the COVID-19 pandemic.
